If you have a computer on Windows 11 with a wireless (Wi-Fi) network adapter, you just have to click on the network icon present in the taskbar, then click on the arrow to the right of the Wi-Fi icon.

Then, select the Wi-Fi network you want to connect to and click on the "Connect" button.

Provide the password for this Wi-Fi network (if password protected), then click Next.

Wait while verifying the network configuration.

Once connected to this Wi-Fi network, the status "Connected" will appear.

Click the "i" icon to the right of the Wi-Fi network you just connected to.

As you can see, by default, Windows 11 will always choose "Public" as the network profile type.
If you are connected to a public Wi-Fi network, this will protect you from hackers.

But, if you are connected to your own wireless network (Wi-Fi) at home, we advise you to select "Private" to authorize in particular the discovery of other computers present on your network and the sharing of files on Windows.
